What is the telephone country code for Austria?

Austria is country code +43. Note that you must omit the trunk prefix 0 from the Austrian number when calling internationally. For example, Vienna's area code 01 becomes +43 1.

(The plus sign means "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but North America (USA, Canada, etc.) uses 011, Japan uses 010, Australia uses 0011, and many other countries use different prefixes.)
